Components of PMD780M
The following figure displays the components of PMD780M.

Detection Field
The Paradox PMD780M Dual-Side View Motion Detector must be installed at a height of 2 meters (6.5 feet) above the floor level. It creates a narrow detection beam pattern from 3m (10 ft) up to 12m (40 ft) on each side, protecting windows, doors, and walls. The detection range can be adjusted by changing the viewing angle of the bottom-facing beams (moving them up and down).

Pet Immunity
The PMD780M detector offers pet immunity for animals weighing up to 40 Kg (90 lbs). When an animal of this size moves close to the ground, it cannot cross enough beams at once to trigger an alarm. This minimizes false alarms caused by pets while maintaining accurate detection of human intrusions.
Physical Mounting
To mount the Paradox PMD780M Dual-Side View Motion Detector:
- Release the screws from the bottom and top of the PMD780M detector.
- Remove the front cover, and then remove the main unit from the backplate.
- Fix the backplate on the wall.
- Reattach the main unit to the backplate.
- Remove the battery tab (present only if the battery is included with the product) from the battery holder. Ensure that the three AA Lithium batteries in the compartment are installed with the correct polarity.
- Connect Battery Connector. The PMD780M is powered on.
- To adjust the detection range:
- Inside the front cover, slide the white tab next to the lower lens up or down on the side you wish to adjust, based on the detection range given below:
- 00 – 12m
- 50 – 10.5m
- 100 – 7.5m
- 150 – 5.25m
- 200 – 3m to 5m
- After adjusting the white tab, lock it into the nearest slot.
- Inside the front cover, slide the white tab next to the lower lens up or down on the side you wish to adjust, based on the detection range given below:
- To adjust the horizontal beams with respect to the wall:
- For the beams parallel to the wall (0 with the wall), slide the lens tray until it aligns with the top edge of the lens holder.
- For the beams at a 3 angle from the wall, slide the lens tray until it aligns with the bottom edge of the lens holder.
- Reattach the front cover and tighten it using the screw at the bottom.
Power-up Sequence
During the power-up sequence, the LED will flash five times red if the device is not paired to the console or five times green if paired to the console. The PMD780M waits between 0-10 seconds before connecting/pairing with the console. If the cover of the device is open, green and red LEDs will flash quickly.
To expand your security system and connect additional devices, you can integrate the PMD780M with modules such as the Paradox RTX3 Wireless Expansion Module, which allows seamless wireless expansion for your Paradox M system.

Press and hold the Learn button for 8 seconds to reset the device to its default settings. Reset is indicated by the LED flashing red three times.
Upgrading Firmware
To upgrade the firmware:
- In the Hardware tab, tap on the device > Check for Upgrade.
- If an upgrade is available, tap Upgrade when prompted.
- The process may take a few minutes.
- Keep track of the progress in the BlueEye application to ensure that the upgrade is completed successfully. Both the Installers and owners can perform the upgrade.
Signal Strength and Transmit Power Monitoring
The BlueEye application provides insights into each device’s received signal strength and transmission power to optimize performance. To view the RSSI and transmit power range.
- When in the Hardware tab, tap the icon next to the Wireless tab. A pop-up window with the RSSI and transmit power range is displayed.
- Maximum power transmitted by PMD780M:
- 868 MHz: +14 dBm
- 914 MHz: +22 dBm

Tap on any listed device to view signal strength and additional device metrics. The following parameters are displayed for each device:![]()
- P – Received signal strength at the panel
- N – Received signal strength at the device
- Transmit power of the device.
- Current temperature reading of the device.
- Battery level of the device
A higher P and N value indicates stronger and clearer communication between the console and the device.
- If P is low, the console struggles to receive signals from the device.
- If N is low, the device struggles to receive signals from the console.
Power transmission impacts only P
- When power transmission increases, the P value at the console generally improves, as a stronger signal is sent.
- If the P value is good, the device can reduce its transmission power to save battery life.
Walk Test
After powering on the detector or opening/closing the cover (if already powered on), the detector enters a walk-test mode for 15 minutes. Perform the following walk test to ensure the motion detector detects movement in the intended area.
Steps:
- Walk across the detection field, moving in and out of the detector’s range.
- Observe LED Indications.
- If the motion detector doesn’t pick up movement as expected, adjust its height or location and re-test.
With Sensitivity set to High and Detection Energy set to Fast, then crossing two beams is detected as a movement. With the Sensitivity set to Low, the amount of movement required to generate detection is doubled. The detector exits the walk-test mode after 15 minutes. To reactivate it, open the cover of the device to trigger the tamper switch, and then close the cover.
Cool-Down Mode
The PMD780M motion detector indicates detection with a 3-second green LED display (or 3-second red if the detector is not paired or connected to the console). After two detections within 3 minutes, the PMD780M enters a cool-down mode to conserve battery life.
